Another object of the invention is to provide an apparatus of this kind in which the various parts are easily dismountable for cleaning.

Another object of the invention is to provide an improved timing means for controllinothe distributing means.

Knother object of the invention is to provide means for preventing the overflow of mill from the treated tanks to the untreated tan s. I

Another object of the invention is to provide improved covers for the tanks and apparatus for controlling said covers.

Other objects of the invention are to improve generally the simplicity and efiiciency of such devices and to provide apparatus of this kind which are durable, economicalv to manufacture and operate and which will not get out of order. I

' Still other objects of the invention will appear as the description proceeds; and while herein details of the invention are described, the invention is not limited to these since many and various changes may be made without departing from the scope of the invention as claime The inventive features for the accom lishment of these and other objects are s own herein in connection with an improved milk holding apparatus which, briefly stated, in-

cludes a plurality of tanks and means including a rotary turret adapted to be advanced to cooperative relation with the tanks successively to withdraw treated milk or other liquid from one tank and then to fill the emptied tank with liquid to be treated. A

yieldable drive means including a drum and weighted cable serves for driving said rotary turret by fractions of rotations as controlled by an esc'apement acting on said drive means for holding said rotary means in operative position a proper length of time for withdrawing and supplying the'liquid until released by a timing means for releasing the escapement' after this length of time has been consumed.

Ulamp nuts 91 on the threaded ends 0 said bolts are adapted to seat on said shoulder lugs 95 when the bolts are between the lugs, thereby to hold said movable frame against upward movement.

Said open seats 94 and inverted chairs 103 mounted on the upper part of said chamber. respectively receive projecting pins 104 and 105 of brackets mounted on said posts and the lower part of said chamber when said posts are raised, thereby to raise said chamber and turret to the position of Fig. 2, for purposes of disassemblingand cleaning.

Theturret rotating means.

' or drum shaft 116 mounted in said bearing bracket 45 and passing through said wall is operatively connected to said drive vertical shaft by'means of equal beveled gears 1'17 and 11.8 whereby the shafts have equal speeds. A drum in the drum housing loosely mounted on said drive shaft receives a cable 121 wound around said drum and disposed under a pulley 122, under the table and pulleys 123 and 124 at op osite ends of a cross beam 125 (Fig. 1) o a transverse middle frame having posts 126 fixed on oppositesides of said table.- The cross beam 125 is disposed a considerable distance above said transverse plate member 16 and the movable frame 71, 72;. A weight 127 ,at the free end of the table tends to unwind the cable and revolve the drum.

The drum winding means. A winding shaft 130 (Fig. 5) rotatably mounted in the'outer wall 112 of'the drum housing carries a pinion 131 meshing with said winding gear .132 fast to one end of the drum. A crank 133 (Fig. 3) on said winding shaft serves as a means whereby said cable is wound up. An escapement disk 135 (Fig. 5) mounted fast on said drive- .sha-ft is provided with a hub 136 having ratchet teeth 137 engaged by a pawl 138 pivotally mounted on a pivot pin 139 on the f inner end face of the drum and adapted to cam over said teeth to permit the drum to revolve in windin direction without revo1v-' ing the drive shatt and to positively engage the teeth to drive the drive,.;. s haft when the drum is rotated by the weiglit. -.-.-v I

The eecapement. r

A series of escapement pins 140 (Fig. 6) mounted 60 apart on the face of said disk near the periphery thereof cooperate with a pawll'ever 141 pivoted tosaid intermediate wall 113 and provided with a shoulder 142 adapted to. engage an one of said .escape inent pins to hold sai turret in any one of its operative positions. A pair of guide pins 144 mounted on saidintermediate wall support an actuating slide bar 145 provided with an upper camrecess 1.46and between the edges with longitudinal slots 147 received on said guide pins to guide the bar, and with a lower marginal recess 148 receiving the free end of the pawl lever to move the latter from operative latching position or inoperative releasing position. A spring 149 is tensioned between said bar and a staple on the intermediate wall for drawing said bar and pawl lever to unlatching position to release the disk. A cam lever 150 pivoted to said intermediate wall or artition 113 has a cam lug 151 at its free en engaging in said cam recess 146 whereby the cam lever is raised when the bar is moved by said spring for a purpose which will be later explainerh Said bar 145 is provided at its lower edge.

with an elongated intermediate notch 154 j with a shouldered pin fast on said slide bar and enga cable by said cam edge 158 as said slide ar and pawl are moved to latching position and engageable by said shoulder edge 159 to hold said bar and pawl ave lever in latching position after they been restored.

A vertical solenoid mounted on said wall 113 carries therein an armature 166 disposed beneath the free end of said latch lever 155 and provided with a collar 167 fast thereon resting on the solenoid normally holding the armature with its upper end projecting less than the lower end. Electric timm means energize said solenoid at state intervals to raise the latch lever and release the escapement permit said disk 135 and turret 48 (Fig. 3) to move one step.

The electric timing means. A hollow column 170 mounted on said box over an opening over said cam lever 150 carries a 0100 case 172 (Fig. 5) provided with an inner annular shoulder 17 3 on which,

' jecting through the partition and carrying a friction wheel 178- fast on the arbor.

Up er and lower guide brackets 180 and 181-( ig. 6) mounted on said partition receive a contact bar 182 slidable in said brackets and provided with a laterally turned upper contact end 183 limiting its downward, movement by engagement with the upper bracket, said bar being intermediately enga'geable with said friction wheel on the side of the wheel. A bell crank pressure ever 185 pivoted at its elbow part on said fibroid partition 17 5 has its lower arm laterally turned disposed with its free end 186 resting on alifting rod. 187 resting on saidv cam lever 156. A spring 188 tensioned block may be adjusted.

between the upper arm 1'89 and a pin in said partition presses roller 190 carried by said arm against the contact bar 182 and the latter in frictional engagement with the friction wheel 178, whereby the contact bar rises as the wheel rotates.-

Upper and lower bearing brackets 191' and 192 above said guide brackets carry an adjusting screw 193 rotatable insaid hearing brackets and provided at the upper end witha manipulating head194. Said screw supports a block 195 having a thread- -ed bore received on said screw and having a fiat face 196 (Fig. 5) engaging said parti tion to prevent turning when the adjusting screw is rotated, whereby the height, of said An insulated contact plate 197 (Fig. 6) carried on the lower face of said block is engaged by said con tact bar when the latter is raised from the guide bracket 180 to the cont-act plate by thefriction wheel, within a length of time depending upon the height to which the block 195 is adjusted. I

An insulating disk 200 mounted in said opening in the box having a central ening therein for the reception of the li ting rod su ports contact members 202 passing through said disk and carrying contact springs 203- engaged by contact pins 204 passing through an insulating plug 205 in said column near the lower end thereof and also provided with a central opening for said lifting rod. A suitable source of" current 208 is "connected by conductors in series with said solenoid between said members 202 and. therefore with the pins 204.

Spring contact plates 215 and 216 (Fig. insulated onthe back of said ease and electrically connected by conductors 217 and 218 (Fig. 6) to said contact pins 204'are i engaged by contact rods 219 and 220 passing through said partition and connected by conductors 221 and 222 with said insulated plate 197 and the lower guide bracket 181 respectively.

Operation of the timing means an escapement means.

When the eontactbar 182 comes into engagemnt with the insulated contactl plate 197, current passesthrou h the circuit 'ineluding said source 208, so enoid 1 65, contact bar182and insulated plate 197, thereby en: ergizing said: solenoid, raising said core 166 and latch lever 156, releasing said sliding bar 145, said-latchjpawl 141 and said escape- -ment di'skg135, thusraisin' the cam lever" tact bar, thus permittingthe contact bar to 150,said lifting rod 187 an 'saidylower arm 186 and moving said. roller 190 from the confall to break'said circuit. When the escapementdisk 135'is thus released, it'movest until the nextescapement pin 140 engages end said shoulder 155 of the slide bar thereby to restore the slide bar to latched position, thus permitting said cam lever 150 and the lifting rod to fall and said roller to again engage said contact bar, to cause said bar to rise again and cause the repetition of the above operation. The heightof the bracket 180 is so selected and the height of the block 195 and plate 197 is so adjusted relative to the speed of the friction wheel 178, that the laterally turned end will travel from the upper bracket 180 to the plate 197 in the exact length of time required between the succcssive step by step movements of the turret.

i The gouernor.

In order to prevent the too rapid rotation of the turret and chamberl provide a governor 225 (Fig. 3-) comprising afixed collar 226 fast onthe shaft, and an outwardly spring pressed slidable collar 227 together siderable distance above the outer ends of the tanks, carry link rods 242 pivoted on the portions of the top bars and normally pending to near the outer ends of the tanks. Covers 243 normally respectively disposed over'the two groups of tanks and hinged as at 244 to said links each comprise an intramarginal plateau, slopes 246 around said plateau, a flat margin 247 (Fig. 7) disposed around said slopes over the outermost gutters, and an innerendplatform 248 disposed adjacent to said turret and over said radial p1pe portions 36 and meeting the adjacent platform, at the. midplane of the ap aratus. 1

lpper and lower bolt-{brackets 250 and 251 mounted near the ipper ends of said link rods carry bolt members slidable in 'the-bevels of said bolt heads an adapted to receive the bolt heads when the covers are raised to near said link rods, whereby the covers maybe balanced under said bars matter.

Operation of the apparatus as a whole.

The Operation of the apparatus is simple and obvious from the foregoing and now need beonly briefly summarized.

Milk to be treated is supplied from the pasteurizer to the pipe 77 at such a rate that the milk passing through the pipes 77 and 80 (Fig. 3), the openings 68 and 57 the channel and the pipe will fill a tank in the length of time required for the laterally turned end 183 (Fig. 6) of the contact bar 182 to rise from the upper bracket 180 into contact'with the plate 197.

At the same time milk is being drawn from the tank next in advance. by means of a suction pump (not shown) acting'through the pipes 78 and 85 (Fig. 3) the duct and pipe 35, sothat the advance tank is empty by the time the preceding tank is filled.

\Vhen the above mentioned contact takes place, the solenoid 165 (Fig. 6) is energized, the escapement is released and the turret moved throu h an angle of 60 to bring the opening 57 (Fig. 3) into register with the port 32 communicating ,with the tank that has just been emptied, and the downturned portlon 58 into register with -the port in communication with the tank in advance of the one that has just been emptied.

The above operation is repeated until all of the tanks are emptied and filled, and this circle of operations is repeated as long as desired or until all of the'milk is treated or until it is desired to clean the apparatus.

The rate of flow of milk to and from the tanks, the size of the tanks, and the time interval between impulses of the timing,

apparatus, are all such that the milk is left in the tank the required length of time for treatment during the time required to make the cycle of the tanks.

When it is desired to clean the apparatus, the covers 243 are slid from the position of the solid lines of Figs. 1 and'7 back to the position 243 of Fig. 7. The cover is then swun through the position 243" of Fi 7 to coking position relative to the lin s 242 to permit the bolt 253 to lock in the striker 255, so that the cover mafy swing to the osition of the dotted lines 0 Fig. 1. With tlie covers thus removed, the pipes 35 may be disassembled and these pipes and the tanks and gutters may becleaned.

In order to clean the turret and associated parts, the pipes 77 and 78 and 80 (Fig. 3).

' then are discOImcctcd from the sections 73 and 74.-

v and the shackle bolts 97 are unfastened, permitting the movable frame to rise, carrying the socket 83 from the axial pipe '85 and bringing the seat 94 and finger 105 into engagement respectively with the finger 104 and the chair 103, thus raisingthe surge chamber and the turret secured fast thereto to the position of Fig.2. This permit-s the easy removal of the cover 66. the parts 83, 85, 87, 88 and 89 and the plugs 62, 63, whereby these parts, the faces 28. 65, channels 30 and ducts 60 may be easily rlcaned. The parts are easily reassembled in the reverse manner.

Continued suction in the emptying duct necessary for the proper operation of the machine tends to suck into the downturned portion 58 (Fig. 4) milk immediately adjacent thereto on the ground lower surface In order to prevent this suction extending to the filling opening 57 and thus draw untreated milk from the filling opening into the emptying duct, thus to contaminate" the treated milk, the radial suction-breaking grooves are provided in said surface 55 to break up. or limit. said suction by establishing a passage communicating with the atmosphere. so that the suction will draw in a bit of air instead of untreated milk from the filling opening 57.
